Ok I am using Heater3
Duet Wifi 2
here is my updated config

; BLTouch - Heaters
;M307 H7 A-1 C-1 D-1 ; Disable the 7th Heater to free up PWM channel 5 on the Duex board.

; Z-Probe

M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H10 F800 T2000 ; set Z probe type to bltouch and the dive height + speeds
G31 X20 Y0 Z3.3 P25 ; Z probe trigger value, offset in relation to nozzle. And trigger height adjustment

Currently im getting this error

for wiring I have the BLTOUCH

White Wire (Z signal) = Z Probe IN
Orange (Servo Sig) = Heater3
Red (5v) = +5V
Brown (GND) = GND

That looks good.. These V3 /config.g files are complicated. More so than with versio 2.x I think. Have you tried it

M950 H7 C"nil" ; Disable heaters h7 to free up pins

One change.. Change:
M950 H7 C"nil" ; Disable heaters h7 to free up pins

to

M950 H3 C"nil" ; Disable heaters h3 to free up pins

Adamfilip

I managed to get it to deploy in tests but when I run homeall
it gets to the point where it centers the head

then it gives me the error

Hallo, can you over a Macro or a G-Code push the BLTouche Pin in or out.
I have the BLTouch config like you and the BlTouch don´t move the Pin.

I have the BLTouch wired on Heater3 (PIN8) on the Duet Wifi Board.
i take the G-Code to test M401 / M402
or
M280 P3 S10 I1
M280 P3 S160 I1
M280 P3 S120 I1
nothing move it.

With the old Firmeware 2.05 the Pin Move in and out.

Have you also adapted deployprobe.g and retractprobe.g?

@CupaCabra said in BLtouch with Reprap Firmware 3.0:

M280 P3 S10 I1
M280 P3 S160 I1
M280 P3 S120 I1

Now you have to use
M280 P0 S10
M280 P0 S160
M280 P0 S120

CupaCabra

Hello,
yes i have but i don´t now is it right.

deployprobe.g
M280 P3 S10 I1

and in retractprobe.g
M280 P3 S90 I1

i hope there are right

DIY-O-Sphere

change P3 to P0 and remove I1

CupaCabra

@DIY-O-Sphere
i change the Code in the Config now an test it.

CupaCabra

It´works with
M280 P3 S10 ......

thx so lot

droftarts

@CupaCabra Great! Please post the 'Z-Probe' section of your config.g to show how you resolved this!

Also, you don't need to unassign the heater channels in RRF3 with M950 H3 C"nil", as they are not assigned by default. Only a few pins are assigned by default, and only need to be unassigned if you use them for something else; see https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Duet_2_WiFi_Ethernet_and_Duet_2_Maestro

Now I am confused.
You will find exact your configuration in
https://duet3d.dozuki.com/Wiki/Gcode#Section_M280_Set_servo_position

And we have done it succesfully on a buddys wifi exact that way with heater7.
Are you shure you have update to the stable and not to a older beta.
I think there you had to trigger the heater instead of the servo channel.

The beta would explain that too.

CupaCabra

so i have change the

deployprobe.g
M280 P3 S10

retractprobe.g
M280 P3 S90

if i test with a Marco file
The pin go´s out with S10 und retract with S90

I think it´s right.

Thanks to this thread I've made progress getting my BLtouch to work. I do have a few questions still.

Basic info:
Duet WiFi 1.02 running RRF3
BLtouch V3.1

The BLtouch is wired as follows:
White Wire (Z signal) = Z Probe IN
Orange (Servo Sig) = Heater3
Red (5v) = +5V
Brown (GND) = GND

Questions (I have googled, but can't find clear answers anywhere):

When I start the printer, the BLtouch performs a self test. This results in the pin being up, and the red led on the BLtouch being on. Is that correct?
When I do a M280 P0 S10 the pin drops. The red led is off, but a blue led is on now. Is that correct?
M280 P0 S10 I1 gives the same result. Is it supposed to work with and without the I1 parameter?
M280 P0 S90 retracts the pin, the red led is on as well as the blue led. Is that correct?

Thanks in advance!

You can remove the I1
I have the same optical signalling, so everything looks fine...
